The Wenhams of England and North America

I am curently researching the Wenham genealogy.Wenham is my maiden name.My father is Russell R., grandfather Clarence D., great-grandfather George, great-great-grandfather James; great-great-great-grandfather is James also.His mother is said to be Hannah.I have no further information on her.Great-great James
came to this country in 1847, to Oneida County NY and, in the spring of 1848 came overland to what is now Hebron Township, Jefferson County, Wisconsin.Anyone out there related?There is supposed to be a John Wenham (or was) in Canada who is a close relative.Also, are there any Wenham's in Wenham , Pennsylvania?And... any info on how Wenham, PA got it's name?
One more thing.My ancestors come from Burwash, Sussex County, England from the research I have done so far.
Waiting to hear from anyone out there!
